HERMAN PIETSOH, OF FLATBUSH, NEW YORK.

STENCH-TRA'P.

SPECIFICATION forming part of Letters Patent No. 270,473, dated January 9, 1883.

Application filed July 3, 1882. (No model.)

To all whom it may concern Be it known that I, HERMAN PIE'ISOH, of Flatbush, in the county of Kings and Stateot' New York, have invented a new and Improved Stench-Trap, of which the following is a fttll, clear, and exact description.

The object of my invention is to provide a new and improved trap for preventing stench and foul gases from rising in a soil or waste pipe.

The invention consists in a stench-trap fotmed of two vessels, one contained within the other, into which inner vessel an inletpipe projects from the top of the outer vessel, which inlet-pipeisprovided with anoutwardlyprojecting spontor collar, which can be closed by a git te hinged to astrip hinged to the inletpipe above this spout or collar, whereby when the suction in the soil-pipe is too great the valve opens and admits air, whereby siphoning out of the. water in the inner vessel of the trap is avoided.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cortesponding parts in both the figures.

Figure l is a longitudinal sectional elevation 0t my improved stench-trap. Fig. 2 is a longitudinal elevation of the same, showing parts broken out.

The cylindrical or like vessel A is provided at its bottom with afscrew-threaded outlet-collar, B, which is to be screwed into the upper end of the lower section of the soil-pipe. A pipe, U, passing through the cover D, screwed iii the vessel, A, has its upper end secured to the lower end of the upper section of the soilpipe by a loose screw-collar, E, of the usual construction. A cylindrical or cup-shaped vessel. F, which is smaller than the vessel A, and which is open on top, is contained iii the vessel A, and is helda short distance from the bottom of the vessel A by blocks or strips G, leaving a space between the sides and bottoms ofthe vessels A and F. The pipe G projects into the vessel F, near to thebottom of the same, and this pipe 0 is provided above the vessel F with a short spout or collar. H, which is closed by a gate, J, hinged to a link, K, hinged to a lug projecting from the pipe 0 above the spout. The gate J closes the opening of the spout or collar automatically by its own weight. The water rises in the vessel F and flows over the upper edge of the same, and through the space between the vessels A and F, and through the outlet of the vessel A. The

water in the vessel Ftorms a sealand prevents the gases frotn passing into that part of the pipe above the vessel A. As the water in vessel F is frequently siphoned out by thegreat suction created in the soil-pipe, l have provided the opening H and the gate J, which is opened automatically by the suction and admits air into the vessel A, thereby preventing siphoning out of the water in the vessel F, as the pipe then draws air instead of water.

Having thus fully described my lIlVeIlilOll, I claim as new and desire to secure by Letters Patent- 1. Astench-trap made substantially as herein shown and described, and consisting of two vessels contained one ithin the other,and an inlet-pipe passinginto the inner vessel, which pipe is provided with an outwardly-opening air-valve, as set forth.

2.-In a stench-trap, the combination,with the vesselA,of' the vessel F, contained there in, the inlet-pipe G, extendingdown into the vessel F, the short spout or collar H, and the hinged gate J for closing the same, substantially as herein shown and described, and for the purpose set forth.

'3. lit a stenchtrap, the combination,with the vessel A, otthe vessel F, contained therein, the inlet-pipe 0, extending down into the vessel F, the short spout or collar H, the gate J, and the strip K, hinged to the gate J,attd the pipe 0 above the collar H, substantially as herein shown and described, and for the purpose set forth.
